Title: Semiconductor laser
Inventor: MATSUMOTO KENJI
IPC: H01S5/00
Filed: 1987-10-26
Abstract: PURPOSE:To reduce a capacitance value by a method wherein a current-blocking layer (a p-n junction) occupying the majority of the capacitance value of a device is removed except a mesa part and a bonding pad part. CONSTITUTION:A current-blocking layer is composed of a semiconductor layer 5 with a high resistivity value and of a semiconductor layer 6 whose resistivity value is lower than that of the layer; an electrode 8 is formed directly on the semiconductor layer on the side of a growth layer; the electrode 8 in a region near an active layer 2 and other than a bonding pad 11 and the semiconductor layer 6 whose resistivity value is low in the current-blocking layer are removed. Accordingly, even when the current-blocking layer is removed down to the blocking layer 5 so as to remove the blocking layer 6, a junction capacitance value is decided substantially by an area of the blocking layer 6. By this setup, the capacitance value can be reduced.

IPC: F16S3/00
Filed: 1993-10-27
Abstract: PURPOSE:To increase the average squashed load by a heat treatment, to control the increase of the squashing pitch without increasing the strength as the whole, and to stabilize the squashing mode, by setting the heat treatment part in a specific scope from the tops of the corners while leaving a nontreating part between the corners. CONSTITUTION:In an effective width (a) from the tops of the corners K to both sides H of a high strength member 10, a heat treatment is applied locally and the strength is increased at the heat treatment part N shown as oblique lines more than the other parts. The heat treatment part N is formed by setting laser beams in an effective width (a), for example, so as to radiate the corners K. As a result, the heat treatment is carried out locally efficiently by limiting the scope. The effective width (a) is set as a=4. nt<0.46> (where t is the thickness of the plate, and n is the number of corners) or higher. Consequently, an impact energy is absorbed mostly by the plastic deformation of the scope of the effective width (a) from the tops of the corners K, so as to increase the average squashed load Pave, and a large energy can be absorbed securely.
